OlL-SEPARATOR.

' SPECIFICATION forming part of Letters Patent No.-752,066, datedFebruary 16, 19 04.

Application filed April 1, I903. Serial No. 150,600. (N0 model.)

To all whom, it may concern:

city of Chicago, Cook county, State of Illinois,

have invented an Improvement in Oil-Separators, of which the followingis a specification.

It is one of the objects of this invention to more effectively andcompletely accomplish the separation or removal from steam of the oilheld in suspension therein.

Owing to the centrifugal motion of the steam under high velocity,aportion of the oil is thrown outward upon the inner walls of thepiping, and one of the features of this invention relates to theemployment of a bafi'le at the inlet to collect this oil and dischargeit. This baflie is preferably acopper ring having a curved edgeextending transversely about the inlet and having an opening at thebottom through which the oil and water may pass into the bottom of theseparator or into the re ceiver. As it is usual to make oil-separatorsreversible, one of these bafiies may be placed at each end, so thateither'end may act as the inlet.

It is also the object of my invention to render the separator especiallyadapted to vacuum conditions, and to this-end water is supplied to theseparator in the form of a shower or spray to assist in condensing thesteam as well as in removing the oil. When the water is supplied to thesurfaces of the baffles it will render them more efficient in removingand discharging the oil. chamber is arranged in the top of. theseparator, from which the water is supplied through perforations orspray-pipes to the interio'r'of the separator and when supplied to thebafiies will form a running film on their surfaces.

The water is preferably supplied byasprinkler-head,- which may be maderemovable.

In the drawings, Figure 1 is a longitudinal vertical sectional View of.an oil-separator embodying the invention. Fig. 2 is a horizontal sectionof the same on the line A B of Fig. 1. Fig. 3 is an end elevation withone-half in transverse vertical'section on the line C D of Fig. 1. Fig.tie a perspective view of one of the detached bafIie-plates. Fig. 5 is alongitud inal sectional view of part of the separator,

- a perforated plate 6.

For this purpose a water-- showing the water-supply to the end baflies;andFig; 6 is a vertical sectional View on the line E F of Fig. 5.

The body of the separator 64 is provided with an inlet 6 for the steamat one end and an outlet 0 at the other. The receiving-chamber d 'iscarried by the body a and communicates with the interior thereof,preferably through Arranged within the separator a between the steaminlet and outlet are-a series of baffles f, adapted to catch the oil.These baffles may be of any suitable form; but, as shown, they consistof vertical plates having their vertical edges curved, as at f to catchand retainthe oil in the steam. The baffles f are fastened to theperforated base-plate c with the curved vertical edges f preferably inline with perforations e in the plate, so that the oil extracted bythese curved edges may pass through the perforations into the receiverd. The curved edges fon the plates fare preferably curved in relativelyopposite directions, as shown, so that the bafiies will be equallyeffective whether the steam be introduced from one side or the other. Sofar as the separator has been described it is of Well-known constructionand has been described merely for the purpose of illustrating myimprovements, which are not, however, restricted to use in connectionwith separators of this particular construction. As the steam at thepoint of entrance is mostheavily charged with oil and as this oil is toa great extent deposited on the walls of the piping, I arrange a battle9 directly at the inlet. annular, and consists of a plate having acurved or hooked edge extending about the inlet, but open at the bottomto allow the oil caught by it to escape into the bottom of the body aand pass into the receiver d. As it is desirable that the separatorsho'uldlbe reversible, so that either opening 6 orcmay be used as theinlet, a bafilefgshould bearranged at extracting the oil from the steampassing through the chamber a, they are kept wet.

This baffle, as shown, is substantially of oil upon the surfaces of thebaffles will be prevented. By these means the efficiency of the bafliesin extracting the oil will be greatly increased.

My preferred method of supplying the water to the baffles is by means ofa sprinkler-head arranged above the perforated distributingplate i andreceiving the water from a suitable supply-pipe 1'. To enable thesprinklerhead to be removed when desired, it is preferably carried by aremovable bushing m in the body a above the plate c and is connectedwith the supply-pipe r by a suitable coupling n.

In the separator shown in Figs. 5 and 6 the water is supplied to the endbaflies 9 also. For thispurpose the. water-chamber h is shown extendedat its ends and provided with water-tubes 7c, terminating insprinkling-heads 0, arranged adjacent to the upper portion of the insideof the baflies, by which the water may be thrown in a shower both uponthe curved surface of the baflies and across the opening of theseparator.

The free shower of water will assist in condensing the steam and renderthe separator especially adaptable for vacuum conditions. For likereasons the whole or part of the water passing through the perforatedbase 6 into the body of the separator may be allowed to fall in a freeshower out of contact with the baflles f. When, however, the separatoris not to be used under vacuum conditions and an increase ofcondensation is not desired, the water may be supplied only to thesurfaces of the baflies f and g.

I do not limit myself to the details of construction shown, as they maybe varied without departing from the invention.

What I claim as new, and desire to secure by Letters Patent, is asfollows: 1. In an oil-separator, the combination with the body having aninlet and an outlet and baffles arranged transversely between said inletand outlet, of a battle located at the inlet and consisting of a platewithin the inner walls of the inlet and having its inner edge extendingin a transverse lip about the inlet.

2. In an oil-separator, the combination with the body having an inletand anoutlet and baffles arranged transversely between said inlet andoutlet, of a baffle located at the inlet and consisting of a platefitted within the inner walls of the inlet and having its inner edgeextending in a transverse lip about the inlet but open at the bottom toallow the oil and i water caught thereby to escape.

3. Inan oil-separator, the combination with the body having an inlet andan'outlet and baffles arranged transversely between said inlet.

and outlet, of a baffle located at the inlet and consisting of a platefitted within the inner walls of the inlet and having its inner edgeextending in a transverse lip about the inlet curved forwardly towardsaid inlet. I. In an oil-separator, the combination of body providedwith an inlet and an outlet and having a perforated plate at the top,bafiies within said body between said inlet and outlet adjacent to theperforations in said plate,

and means to supply water to the surfaces of said baflies through saidperforated plate.

5. In an oil-separator, the combination of a body provided with an inletand an outlet and having perforations in the top and bottom, a receivercommunicating with the interior of said body through the perforations inthe bottom, bafiies between said inlet and outlet arranged adjacent tothe perforations in the top and bottom, and means to supply water to thesurface of said baffles through the perforations'in the top.

6. In an oil-separator, the combination of a body having an inlet and anoutlet and provided at the top with a closed water-chamber communicatingwith the interior of the body through perforations, and at the bottomwith a receiver also communicating with the interior of body throughperforations, baflies within the body extending from the perforations inthe top to those in the bottom, and means to supply water to saidwater-chamber."
